Nitrogen gas flows through a long, constant$-$diameter adiabatic pipe. It enters at $102\mathrm{.}0$ psia and $120F$ and leaves at $50$ psia and $70F.$

Calculate the velocity of the nitrogen at the pipe's inlet and outlet. The specific heat of nitrogen at the room temperature is

$c_P=0\mathrm{.}248Bt\frac{u}{l}bm*R.($Round the final answers to three decimal places.$)$

The velocity of the nitrogen at the pipe's inlet is

$f\frac{t}{s}.$

The velocity of the nitrogen at the pipe's outlet is

$f\frac{t}{s}.$
